The paper brings details of a simple method for rapid synthesis of triangular silver nanoparticles and their characterization. The method presented proceeds with a simple reaction in aqueous solution at ambient temperature and nanotriangles are synthesized in a few minutes. The formation of triangular nanoparticles was investigated by UV-VIS spectroscopy. Transmission electron microscopy (TEM) images of nanoparticles show that resulting triangles are truncated. The concentration of reactants and pH were found to have influence on the shape of resulting nanoparticles. These results indicate that hydrazine and citrate are necessary for formation of triangular nanoparticles.
